B. Description of Related Art

Sanitation is an inevitable aspect when it comes to promote hygiene and health to people by preventing them from contacting human waste and sewage. Traditionally, people would move to outhouses or the like are situated out of site and away from people and social gathering to use them as toilets. Distance was a primitive solution for privacy from others experiencing nuisance smells and embarrassing noises that are associated with elimination during that time. Then conventional toilets are configured with a storage tank that collects an amount of flush water that is supplied from a water main or water supply line were used. Upon the actuation of a lever or other control mechanism; a valve, such as a flapper valve, is opened and the collected flush water is released from the tank into a bowl to remove the grime. However, the dilemma of smell and noises associated with in-home toilets have yielded a courtesy flush, scented sprays, running of water to mask noises, and even the strike of a match.

Currently, the in-home toilets with the traditional flush toilet system fails to eliminate the odors and grime completely as the flushing mechanism does not allow adequate flow of water in the bowl to remove the grime on a constant basis. Things get worse when it comes to home with guests or in a public setting as the repeated use of the toilet causes embarrassment among the users. The noise is also a factor that induces embarrassment and shame on the users when they experience it. Further, the unpleasant odors cause lot of uneasiness to the occupants of the home and in worst cases, it could lead to numerous health issues.

In some cases, the grime contents start getting deposited on the toilet bowl creates surface tension and material of the bowl disintegrates the structure of the bowl. Further, all the available flush toilets require lot of pressure to flush the water to remove the contents and some people tend to use the flush repeatedly which creates noise as well as the amount of water spent increases. Sometimes, noise reduction is created due to the action of deposits being dropped into moving water, preventing the surface tension from breaking, which occurs when something is dropped into still water

Therefore, there is a need for a toilet flush assembly with a constant water supply system to remove waste immediately once deposited to maintain a clean and hygienic environment.

With a constant flush, unsanitary deposits are removed right away. This eliminates odors from building due to the deposited contents of the toilet bowl 104 sitting stagnate, for even a small amount of time. With moving water, contents will flow down gently, therefore no dropping sound is created nor splash up from waste contaminated waters. Some secondary sounds will be masked by the sound of swirling water. It is not required to do a wasteful courtesy flush that may also create unsanitary splash up. As the waste is being removed immediately with each deposit, the risk of clogging is deceased. The bulk of contents in the toilet bowl 104, at a given time is dramatically reduced and reduces the tank pressure needed to overcome large bulk with a single flush action, as seen with today's toilets. No embarrassing repeated flushes is required, thus reducing time spent in the bathroom and noise that is created with doing so. The embarrassment of close quarter elimination is not only reduced but omitted with the action of the constant flushing mechanism. The constant flush toilet assembly 100 helps to eliminate the problems associated with sounds, sanitation, and unpleasant odors generated with the use of a toilet. An on/off valve 130 helps the user to activate the constant flush toilet based on their requirements. The constant flush toilet assembly 100 is easy to install and cost-effective and could be adapted to fit already existing designs of toilet.
